The possible options are:
101
<emphasis>Note:</emphasis> all option values are subject to
102
start time expansion, see <xref linkend="expansion"/>.
105
Unknown options are ignored. The used options are as follows:
116
<term><literal><varname>timeout</varname></literal></term>
118
<synopsis><literal>timeout = </literal><replaceable
122
The timeout is how long the server will wait for a
123
successful checker run until a client is considered
124
invalid - that is, ineligible to get the data this server
125
holds. By default Mandos will use 1 hour.
111
<term><option>approval_delay<literal> = </literal><replaceable
112
>TIME</replaceable></option></term>
115
This option is <emphasis>optional</emphasis>.
118
How long to wait for external approval before resorting to
119
use the <option>approved_by_default</option> value. The
120
default is <quote>0s</quote>, i.e. not to wait.
123
The format of <replaceable>TIME</replaceable> is the same
124
as for <varname>timeout</varname> below.

The format of <replaceable>TIME</replaceable> is the same

Whether to approve a client by default after

157
is <quote>True</quote>.
163
<term><option>checker<literal> = </literal><replaceable
164
>COMMAND</replaceable></option></term>
167
This option is <emphasis>optional</emphasis>.
170
This option allows you to override the default shell
171
command that the server will use to check if the client is
172
still up. Any output of the command will be ignored, only
173
the exit code is checked: If the exit code of the command
174
is zero, the client is considered up. The command will be
175
run using <quote><command><filename>/bin/sh</filename>
176
<option>-c</option></command></quote>, so
177
<varname>PATH</varname> will be searched. The default
178
value for the checker command is <quote><literal
179
><command>fping</command> <option>-q</option> <option
180
>--</option> %%(host)s</literal></quote>.
183
In addition to normal start time expansion, this option
184
will also be subject to runtime expansion; see <xref
185
linkend="expansion"/>.
191
<term><option>extended_timeout<literal> = </literal><replaceable
192
>TIME</replaceable></option></term>
195
This option is <emphasis>optional</emphasis>.
198
Extended timeout is an added timeout that is given once
199
after a password has been sent successfully to a client.
200
The timeout is by default longer than the normal timeout,
201
and is used for handling the extra long downtime while a
202
machine is booting up. Time to take into consideration
203
when changing this value is file system checks and quota
204
checks. The default value is 15 minutes.
207
The format of <replaceable>TIME</replaceable> is the same
208
as for <varname>timeout</varname> below.
214
<term><option>fingerprint<literal> = </literal
215
><replaceable>HEXSTRING</replaceable></option></term>
218
This option is <emphasis>required</emphasis>.
221
This option sets the OpenPGP fingerprint that identifies
222
the public key that clients authenticate themselves with
223
through TLS. The string needs to be in hexidecimal form,
224
but spaces or upper/lower case are not significant.
230
<term><option><literal>host = </literal><replaceable
231
>STRING</replaceable></option></term>
234
This option is <emphasis>optional</emphasis>, but highly
235
<emphasis>recommended</emphasis> unless the
236
<option>checker</option> option is modified to a
237
non-standard value without <quote>%%(host)s</quote> in it.
240
Host name for this client. This is not used by the server
241
directly, but can be, and is by default, used by the
242
checker. See the <option>checker</option> option.
248
<term><option>interval<literal> = </literal><replaceable
249
>TIME</replaceable></option></term>
252
This option is <emphasis>optional</emphasis>.
255
How often to run the checker to confirm that a client is
256
still up. <emphasis>Note:</emphasis> a new checker will
257
not be started if an old one is still running. The server
258
will wait for a checker to complete until the below
259
<quote><varname>timeout</varname></quote> occurs, at which
260
time the client will be disabled, and any running checker
261
killed. The default interval is 2 minutes.
264
The format of <replaceable>TIME</replaceable> is the same
265
as for <varname>timeout</varname> below.
271
<term><option>secfile<literal> = </literal><replaceable
272
>FILENAME</replaceable></option></term>
275
This option is only used if <option>secret</option> is not
276
specified, in which case this option is
277
<emphasis>required</emphasis>.
280
Similar to the <option>secret</option>, except the secret
281
data is in an external file. The contents of the file
282
should <emphasis>not</emphasis> be base64-encoded, but
283
will be sent to clients verbatim.
286
File names of the form <filename>~user/foo/bar</filename>
287
and <filename>$<envar>ENVVAR</envar>/foo/bar</filename>
294
<term><option>secret<literal> = </literal><replaceable
295
>BASE64_ENCODED_DATA</replaceable></option></term>
298
If this option is not specified, the <option
299
>secfile</option> option is <emphasis>required</emphasis>
303
If present, this option must be set to a string of
304
base64-encoded binary data. It will be decoded and sent
305
to the client matching the above
306
<option>fingerprint</option>. This should, of course, be
307
OpenPGP encrypted data, decryptable only by the client.
308
The program <citerefentry><refentrytitle><command
309
>mandos-keygen</command></refentrytitle><manvolnum
310
>8</manvolnum></citerefentry> can, using its
311
<option>--password</option> option, be used to generate
315
Note: this value of this option will probably be very
316
long. A useful feature to avoid having unreadably-long
317
lines is that a line beginning with white space adds to
318
the value of the previous line, RFC 822-style.
324
<term><option>timeout<literal> = </literal><replaceable
325
>TIME</replaceable></option></term>
328
This option is <emphasis>optional</emphasis>.
331
The timeout is how long the server will wait, after a
332
successful checker run, until a client is disabled and not
333
allowed to get the data this server holds. By default
334
Mandos will use 5 minutes. See also the
335
<option>extended_timeout</option> option.
128
338
The <replaceable>TIME</replaceable> is specified as a
144
<term><literal><varname>interval</varname></literal></term>
146
<synopsis><literal>interval = </literal><replaceable
150
How often to run the checker to confirm that a client is
151
still up. <emphasis>Note:</emphasis> a new checker will
152
not be started if an old one is still running. The server
153
will wait for a checker to complete until the above
154
<quote><varname>timeout</varname></quote> occurs, at which
155
time the client will be marked invalid, and any running
156
checker killed. The default interval is 5 minutes.
159
The format of <replaceable>TIME</replaceable> is the same
160
as for <varname>timeout</varname> above.
166
<term><literal>checker</literal></term>
169
This option allows you to override the default shell
170
command that the server will use to check up if the client
171
is still up. By default mandos will "fping -q -- %%(host)s"
177
<term><literal>fingerprint</literal></term>
180
This option sets the openpgp fingerprint that identifies
181
the public certificate that clients authenticates themself
182
through gnutls. The string need to be in hex-decimal form.
188
<term><literal>secret</literal></term>

Base 64 encoded OpenPGP encrypted password encrypted by

the clients openpgp certificate.

Base 64 encoded OpenPGP encrypted password encrypted by
202
the clients openpgp certificate as a binary file.

<term><literal>host</literal></term>
211
Host name that can be used in for checking that the client is up.
